Comparison of Fruit Development and Quality of Korla Fragrant Pear and Its Different Bud Mutations

【Objective】The project aims to provide basis for selecting fragrant pear plant of good quality bud mutation through comprehensive comparison of the dynamic changes of bud mutation types and fruit quality. 【Method】The experimental materials: Korla fragrant bears,bud mutation No. 6,Zaomeixiang bud mutation No. 9 and 10,Sha No. 01 and Xinli No. 2 were from Shayidong Horticultural Farm and Baotouhu Horticultural Farm in 2013. Every other 7 days,30 randomly selected bud mutation fragrant pear varieties were tested and the growth dynamics of transverse and longitudinal diameters were determined. And the data of the external quality and internal quality were measured and analyzed by SPSS 17. 0 software through the analysis of variance evaluation of fragrant pear and its bud mutation types of fruit quality.【Result】The growth rate of Korla fragrant pear was slower than that of the bud mutation pears and there existed certain difference between the embedded substances of both kinds.【Conclusion】The transverse and longitudinal diameters of fragrant pear and its bud mutation type grew into a double S curve,and the fruit quality of Sha No. 01 and Xinli No. 2was better.
